This machine is designed for use in closing the open end'of a box orcarton similar to that shown in Fig.6, having the end flaps a ctand b o,by turning the flaps a a. down onto a form, applying glue or cement tothe inner surfaces of the flaps b and o, turning these flaps'insuccession, the first, as b, onto the flaps a a, and the second, as 0,onto the flap, as 1), subjeotihg the end of the box formed by these'inturned flaps to pressure, and finally ejecting the box from themachine. The flaps a a have heretofore been turned inward by hand, theflap I) being then turned down onto the flaps a Ct by the passage of theglue-roll, which in passing applied glue to the outer surface of theflap b. An important object of the present invention is to apply glue tothe inner surface of the flap b, so that when this flap is turned downonto the flaps 66 a it will adhere thereto and prevent these flaps a afrom lifting up at the inside of the box, glue being then applied to theinner surface of the flap c to affix that flap to the outer ungluedsurface of the flap b.

In the drawings, 5 and 6 represent side or end frames of the machine,these frames being connected at their lower portions by the numbers 7 7and at the upper portions by the hood or plate 8, of substantialconstruction, firmly bolted in place and designed to resist aconsiderable pressure from beneath. Journaled in hearings in theseframes and in the bracket 9 is the main shaft 10, and on the shaft isjournaled a sleeve having the pulleys 11, 12, and 13 fixed thereto andcarrying the belts 14, 15, and 16, the main belt 14also working over anypower-driven pulley (not shown) from which power may be transmitted bysaid belt to the pulley 11. The hub of the pulley 11 has the radialgrooves 17, and adjacent to this end of this pulley is the sleeve 18,fixed to the shaft and having a guideway or slot in which thespring-pressed dog 19, having the head 20, may move toward and from thehub of the pulley 11, connecting said sleeve 18 and its shaft 10 withthe pulley 11 when engaged in one of said grooves 17, so that the shaftwill rotate or by the disengagement of the dog from the pulley-hub torelease the shaft 10 from the driving connection with the pulley. On theshaft 10 are fixed the carrieractuator cam 21, the pressure or liftercam 22, and the ejector-actuator cam 23, Fig. 1.

In the frames 5 and 6 is fixed the shaft 24, on which is journaled thesleeve of the carrier-lever 26, the roller-bearing 27 of which rides onthe face of the cam 22. This lever has studs 28, on which the arms29'and 30 of the carrier-arm 31 are journaled, the arm 29 having theextension 32, to which is secured the bolt 33, which works through thecurved slot 34 in the frame 5 and is secured to one end of the openframe 35, the other end of this frame being furnished with thebearingsleeve 36, working against the face of the cam 21 and held incontact therewith by the springs 37 37, secured to the upper portions ofthe arms 29 and 30 and to pins 38, extending from the side frames 5 and6. The carrier-arm 31 is provided with the adjustable side supports 3939 and with the axially perforated form 40, which is removably securedto the arm 31. In the rear surface of this arm is formed the recess 41,Fig. 4, and in this recess is movably mounted the ejectorrod 42, havingthe outwardly-extending cars 43 43 and adapted at times to work throughthe perforation in the form 40.

Between the frame 6 and the cam 23 is the frame 44, open at its centerto work over the shaft 10 and having the stud 45, Fig. 1, working in thegroove of said cam. Atthe rear of the frames 5 6 is mounted the shaft46, and on this shaft is journaled the sleeve 47, having the lever-arm49, extending inward and positioned to enter between the ears 43 43 ofthe ejector-rod 42 when the carrier-arm 31 reaches its limit of rearwardmovement.

At the upper portions of the side frames 5 and 6 are inwardly-projectingpivots, as 50, Fig. 3, on which are pivoted the side arms 51 51 of theflap-support and foldenplate 52, furnished with the projecting pin 53,carrying a sleeve, the downward movement of this plate being limited bythe finger 54 on thejournaled portion of one of the arms 51 coming incontact with the stop 55 on the frame 5 or in any other suitable manner.

To the front portion of the frame 6 is secured the bracket 56, carryingthe slide-box 57, in which the follower 58 is mounted to reciprocate. Ina bearing of this box is journaled the shaft 59, having a pin 60eccentrically disposed thereon and engaged in the opening of saidfollower. From the shaft 59 extends upwardly the arm 61, connected withthe frame member 6 by the spring 62, carrying the rod 63, on which thewiper-plate 64is mounted to swing, the coiled spring 65 on said rod andfastened to the arm 61 and to the plate 64 being designed to retard theswinging of the plate.

From the frame 6 extends the support 66, in which is journaled the lowerportion of the upwardly-inclined glue-roll shaft 67, the upper portionof this shaft being journaled in a bearing 68, supported from thebracket 56. At the upper end of the shaft 67 is secured the glue-rollframe 69, furnished with a horizontal shaft on which the roll-sections70 are rotatable. At this upper portion of the shaft 67 is also securedthe cam 71, having the downwardly-inclined end portions 72 and 73,extending below the point at which the bearing 53 of the plate 52normally rests and adapted to move under said bearing when said camrotates with its shaft, whereby said bearing may ride up onto the mainsurface of said cam when the cam rotates. On the shaft 67, below thebearing 68, is fixed the cam 74, Fig. 5, having the collar 75, this camand its collar being slotted to receive the spring-pressed dog 76,having the projection '77, so that when at its lowest point of movementunder the pressure of its spring this dog may extend below the lowersurface of the cam 74.

The collar 78 is supported from the bracket 56 and forms a bearing forshaft 67. On this collar 78 is supported the bevel-gear 79, loose on theshaft 67 and having the extension 80, furnished in its upper surfacewith a series of grooves or seats 81, in which the dog 76 may engagewhen at its lowest point of movement.

In the lower portion of the machine-frame is journaled the treadlerock-shaft 82, furnished at one end with the treadle 83 and at the otherend with the lever-arm 84, this arm being bent around the member 6 ofthe frame 6. On the collar 78 is pivoted the bell-crank lever 85, one ofthe arms of which is connected with the lever-arm 84 by the connecting-IIO rod 86, the other arm of this bell-crank lever extending upward andengaging the latch 87,

pivoted to the under surface of an arm 88, ex-

tending from the bearing 68, this latch having a beveled end adapted toengage the projection 77 of the dog76 as the dog is carried around, by"the rotation of the cam 74 and its shaft, so that in riding up thisinclined end of the latch 87 the projection 77 lifts the dog 76 out ofits engagement with the grooves 81 in the extension 80 of the gear 79,while the swinging outward of the latch 87 by the bellcrank lever 85releasesthe projection 77 and perm'its'the dog 76 to be forced downwardby its spring.

At the lower portion of the glue-roll shaft 67 is fixed a collar havingthe cam-finger89,

and on the arm 66 is pivotally mounted the lever 90, having at one endthe plate. 91,

against which the cam-finger 89 may work at times to swing said lever,and at the other end of the lever is mounted for universal i e the latchand is moved outward against the a permanent friction on saidenlargement to pressure of its spring to release the dog from the groove17in the hub of the pulley 11, thus disconnecting this drive-pulley fromthe sleeve 18. e

Embracing the enlarged portion of the sleeve 18 is the friction-strap95, which exerts prevent undue movement of the sleeve under the impulseof the drive-pulley 11 and to retard the movemen t of the sleeve whenreleased from connection with thepulley 11, this fricti on-strap 95being held from movement by,

its engagement with the end of the shaft 82 min any other suitablemanner.

From the rear portion of the frame member6 extends the bracket 96, inthe lower portion of which are hearings in which the shaft 97 isjournaled. At one end ofthis shaft is the pulley 98, over which the belt15 Works, While at the inner end of the shaft is the bevel gear 99,which meshes withthe bevel-gear 79:

on the glue-roll shaft 67. e

On the bracket 96 is mounted the glue-reservoir 100, having b'earings'inwhich the shaft of the glue-supply roll 101 is journaled, the. glue-rollshaft being furnished with the pul-, ley 102, over which the belt 16works, and with,

' the gear 103, which engages with the gear 104,

Fig. 2, on the shaft of any usual form of doctor-roll, whichis rotatablymounted adjacent to the glue-supply roll 101 and isadapted to distributethe glue evenly over the periphery of said roll in,tl1e usual andwell-known mannerin machinesof, this class.

When in position to start the operation of the machine, the variouspartsare in the positions shown in Fig. 1 of the drawings, a box orcartonbeingslipped over the form 40 until its end bears against theadjustable stops 39. til they bear against the surface of the form, theflap I) turned outward and resting on the sleeve of the flap-turner 64and the flap c resting against the supporting-plate 52, it beingunderstood that power is applied to the pulley 11 by means of the belt14 and that the belts 15 and 16, with the pulleys 98 and 102 and theirrelated mechanisms, including the bevel-gear 79, are nownnder operation,while the main shaft 10 and the glue-roll shaft 67 are at rest. Pressureapplied to the treadle 83 will cause the rocking of the shaft 82 in itsbearings, and the free end of the lever 84 will move downward, drawingwith ,it

the rod 86 and swinging the latch 87 out of supportingf engagement withthe dog 77, which under the pressure of its spring will move intoengagement with one of the grooves 81 in the collar of the pulley 79,and as the cam 74, which carries said dog, is fixed to the shaft 67 theshaft 67 and its connected mechanism will rotate with the gear 79. The

The flaps a a are bent down byhand unprimary rotation of the shaft 67effects the swinging of the glue-roll section from the delivery-roll 101and carries the depressed end 73 of the cam-plate 71 under the bearing53 of the support and folder-plate 52, thus permitting this plate tomove down to a point where its upper surface is approximately on a planewith the surface of the form 40. Continuing its rotative movement theshaft 67 now carries the glue-sections 70 successively over the innersurface of the flap I), over the outer surface of the uppermost of theflaps a, and over the inner surface of the flap 0, and glue is appliedthereby to these surfaces. When the application of the glue to the flap6 is completed, the shaft 67 has made nearly one-half of the completerotation and is passing above the form 40. During this movement of theshaft 67 the dwell on. the face of 'the cam 74 has held the rod out-,ward against the drawing action of the spring 62 on' the arm 61 of theflap-wiper 64. The out-away portion of this cam 74 being now broughtopposite the end of the rod 85 per- ,mits this rod to move inward towardthe shaft 67 under the action of the spring 62, which :draws the arm 61and its wiper-plate toward the form 40. ,lpivot folds the flap 1) downonto the flaps a Ct andwipes across the outer surface of the flap buntil the outward curve of the cam 74 reaches the rod 85, and this rodis forced back- ,wardor outward and through its connections ,with thearm 62 swinging this arm and its wiper-plate back to its position ofrest. lDur- The wiper-plate turning on its ing this inward and outwardmovement of the wiper-plate the glue-roll has passed beyond the edge ofthe flap c, and the dependingend 72 of the cam 71 has engaged beneaththe ;bearing,53 of the support and folding- .plate 52 and riding underthat bearing has caused the swinging upward of thelplate 52 to aposition to permit the passage thereun- IIO der of the form 40.with theinturned flaps of the box. At this time the shaft 67, having completed aone-half rotation, the cam 89 at the lower portion of this shaft worksagainst the plate 91 on the pivoted arm 90 and forces that plateoutward, thus causing the swinging of the arm 90 and the rod 92 to carrythe latch 93 out of its engagement with the portion of the dog 19. Thespring working against this dog now forces it along the slot in thesleeve 18 to engage in one of the cross-grooves 17 in the hub of thepulley 11 to connect said pulley with the sleeve 18, and this sleevebeing fixed on the shaft 10 these parts, with the cams on the shaft, arecaused to rotate. The first result of this rotation is to permit thesprings 37 to draw backward the carrier until the bearing 36 of theframe rests in the inwardly-curved portion 21 of the cam 21 to bring thecarrier to the position shown in Fig. 3 of the drawings. In thismovement the outer surface of the flap c wiping under the edge of theplate 52 this flap is turned down onto the flap b. When the carrier hasreached the position shown in Fig. 3, further drawing action of thesprings is prevented while the dwell of the cam 21 between the parts 21and 21 is working against the bearing 36. During this period of rest thecam 22 works under the roller-bearing 27 of the lever 26 and lifts thefree end of this lever, thus compressing the inturned and glued flaps aa, b, and 0 between the surface of the form and the plate 8 to effectthe setting of the glue and securing of the flaps together. When thepart2l of the cam 21 is brought opposite the bearing 36, the springs 37act to draw the carrier to its farthest limit of rearward movement andthe cam 23 has worked on the pin of the frame 44 to effect the swingingof the arm 49,through its connection with said pin 45, to a positionwhere the free end of this arm will engage between the ears 43 43 of theejector-rod 42, the further movement of the cam 23 then causing therapid upward swinging of the arm 49 and the sliding upward of theejector-rod 42 to lift the box from the form 40 with sufficient impulseto throw the box from the machine. Approximately at the time that thecam 22 is working against the bearing 27 of the lever 26 the glue-rollshaft 67 has completed its rotation, and as this rotation is completedthe projection 77v of the dog 76 rides up the beveled end of the latch87, thus lifting the dog 76 from its engagement with the groove in thecollar 80 ofthe gear 79 and disconnecting the shaft 67 from drivingconnection with said gear, the shaft 67 and its mechanism stopping inthe position shown in Fig. 1. After the ejectment of the box the cam 21works to rapidly retract the arm 49 and the ejector-rod 42, so that thecarrier may move beneath the plate 8. The throw of the cam 21 now forcesbackward the bearing 37, thus causing the swinging forward of thecarrier to the initial position to receive another box. When this iseffected, the shaft 10 has nearly completed a rotation and theprojection 20 of the dog 19 rides up the beveled end of the latch 93,this dog being withdrawn from its engagement with the groove in the hubof the pulley 11 to disconnect the shaft 10 therefrom,-while thefriction-strap acts to resist the undue further movement of the shaft10.

As the form 40 is readily removable for the substitution of a form ofdifferent size, this machine may be used for turning in and securing theend flaps of boxes of various sizes.

The wiper-plate 64 is adapted for the use on boxes differingconsiderably in size and is an important element of this machine, as itefiects the turning down of the flap Z) automatically and intermediatethe application of the glue and the turning down of ,the flap 0.

By the use of the automatic means for starting the glue-roll mechanismand for subsequently starting the shaft 10 the operation of the machineis made more rapid and effective, while the automatic stopping of thesemechanisms insures against accident to the operator and brings thevarious parts to rest in the position best suited to the placing of thenext box and for starting operations thereon.
